SOS 7201 ADVANCED SOIL PHYSICS
Lecturer
Dr. Lukman Nagaya Mulumba
Course Type: CORE (M.Sc. Agric. I.)
Course Credits (CU):
3 CU i.e. 45 Contact Hours per semester
Course Duration: 15 weeks (45 hours)
1. COURSE DESCRIPTION
The course introduces students to soil physical environment, radiation, heat exchange, humidity, evaporation.
Properties of Soil-Water System. Movement of water and solutes in multimedia. Water transport in the soil- plant –
atmosphere continuum. Water balance. Soil atmosphere gaseous exchange. Preferential flow; break through
curves, fractal theory.
2. Course Objectives
This course will enable students to learn the basic soil physics principles that govern the behavior of soil.
Participation in the course should enable a student to apply the state-of-art - knowledge and skills in soil-water-plant
relations for sustainable natural resource development.
